Let's divide 260804 by 15
We want to figure out the number of times 260804 can be divided by 15.

On to step 1:
15 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 15

Let's proceed to step 2:
When dividing 26 by 15, we get 1 with a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 11 after subtracting 15 from 26.
Bring next digit (0) of the dividend behind the 11 and repeat the process: 110 / 15

On to step 3:
If we divide 110 by 15, we get 7 and a remainder of 5.
Write down 7 as next digit of the result. 
Result so far: 17.0
If we take 105 away from 110, we end up with 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 15

Moving on to step 4:
If we divide 58 by 15, we get 3 and a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 173.0
The remainder is 13 after subtracting 45 from 58.
Grab the next digit (0) from the dividend, add it to 13, then carry on: 130 / 15

Step 5:
When dividing 130 by 15, we get 8 with a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 1738.0
The remainder is 10 after subtracting 120 from 130.
Take the next digit (4) from the dividend and append it to 10, then repeat: 104 / 15

Going ahead to step 6:
The number 15 fits into 104 6 times, leaving a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 17386.0
Subtract 90 from 104 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 7:
15 can be fit into 140 9 times, resulting in a remainder of 5.
Put 9 as the next digit of the answer. 
Result so far: 17386.9
Deduct 135 from 140 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 8:
15 can be fit into 50 3 times, resulting in a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 17386.93
The remainder is 5 after subtracting 45 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 9:
15 can be fit into 50 3 times, resulting in a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 17386.933
The remainder is 5 after subtracting 45 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The quotient of the division is 17386.933, and the remainder is 0.0005.
